Probably because there is no firm answer :-) :-)

No idea.

Not that I know of.

You didn't say what you are wishing to accelerate and in what
environment (kernel, user, apps)?  That may make your choice
a little easier.

Either way you are going to have to write a driver,  so the effort
there will be similar.  So the difference *may* be in the application
support,

Cheers,
